SPECIFTCATION forming part of Letters Patent No. 743,283, dated November 3, 1903.

Application filed July 14, 1903. Serial No. 165 .419. (N0 model.)

T0 at whom it may concern.-

Be it known that I, NEWTON S. HILLYARD, a citizen of the United States, residing at St. Joseph, in the county of Buchanan and State of Missouri, have invented certain new and useful Improvementsin Adjustable Burglar Proof Window-Fasteners; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others-skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

The objects of my device are, first, to provide a window-fastener adapted'to operate in combination with the top of the lower sash and faces of the side pieces of the upper sash in such manner that it will lock the window securely against the entrance of burglars; second, that willpermit the upper sash to be lowered or the lower sash lifted sufficiently to give free ventilation in a room and at the same time aiford protection from burglars, fgduplicate lugs I I, which are also provided with perforations, said lugs being adapted to and, third, that can be used to permit ventilation only, allowing the upper sash to be lowered to the bottom of the window-casement or the lower sash lifted to the top of the window-casement. I attain these objects by the mechanism illustrated in the accompanying drawings, in which i Figure 1 is an elevation of a closed window, showing duplicate tracks in the upper sash and duplicate braces supported on the lower sash. Fig. 2 is an elevation of a window with the upper sash lowered and locked. Fig. 3 is a vertical section of the track, shown mortised into a face of a side piece of an upper sash and a brace pivoted to a plate rigidly attached on the top of the lower sash and a trip carried on the face of said brace. Fig. 4 is a front elevation of the same. Fig. 5 is a detail side elevation of said brace and trip and the plate on which hinged, the dotted lines indicating the position into which the brace will be drawn by the trip when the trip has been elevated to its full height; and Fig. 6 is a front elevation of the brace, the trip thereon, the guides holding the trip in position on the brace, and the plate to which the brace is pivoted, the dotted lines indicating the trip when in position to adjust a sash to any height. i

Similarletters refertosimilarparts throughout the several views.

In the drawings, A is a window-frame; A,

a window-sill; B, an upper window-sash, and

B a lower sash. In the face of each of the inner sides of the side pieces of the upper sash a spring metal track 0 is mortised. This track consists of a single strip of metal which is fitted closely against the back and wood in order to form said shoulders.

E is a metal plate rigidly attached on the ,top of the lower window-sash. This plate is provided with a bearing fand a lug f, pro- ;vided with a perforation or eye.

H is a brace provided at the lower end with engage with log f and be held in connection by a pin or bolt h, passing through their corresponding perforations, the brace being thus hinged to the top of the lower sash. Projecting from the face of said brace are guides J J, which contain apertures through which the round metal trip K operates on the face of the brace. The upper end of the trip is provided with a swivel that works in a crosspiece L, said cross-piece being adapted to The back ofthe groove travel in the track, being held in position by flanges C C. As shown in Fig. A, shoulders D D are of a width only suflicient to receive the upper end of brace H. As the ends of cross-piece L extend under flanged edges 0 0', they are enabled to travel smoothly up and down the entire length of track 0, trip K, and said cross-piece, thus serving their office of locking and unlocking the brace with said shoulders without themselves ever be coming engaged with the shoulders. As shown by Figs. 3 and 4, there is no position said brace and trip and its cross-piece can assume or into which they can be drawn that will allow them to become displaced on or withdrawn from track 0 except at slot M, which outlet is always at the upper end of the track and at a point above the highest shoulder D. The main object of this slot is to permit the brace and trip to be disconnected from the upper window-sash when it is desired to remove either sash from the window-frame or when for other reason such disconnection is desired.

When sashes are closed and the device is in position both to prevent the entrance of burglars and shut off ventilation, the upper ends of the braces will be in the recesses or notches d d and below and against the lowest corresponding opposite shoulders D D,the crosspieces will be pressing down on the faces of the braces near their upper ends, and the turned trip-lifts O 0 will be engaged from beneath with lugs P P on the faces of the braces. To unlock the device and raise the bottom sash or lower the top sash and secure ventilation either at bottom or top or both bottom and top of window, it is only necessary to release trip-lifts O 0 from their engagement with lugs PP and lift the trips up ward until the cross-pieces have passed off the faces of the braces. The trip-lifts being then swung into position supported by lugs P P, as shown by dotted lines in Fig. 6, the cross-pieces will be held in position to travel freely up and down the entire track as the sash is raised or lowered and the braces will be held by the trips away from contact with the shoulders until the lifts are released from their position above lugs P P. When released, the trips will drop, automatically carrying their cross-pieces into position over the faces of the braces, and the device is ready to lock at the passage of any notch d d and permit the adjustment of a sash at any desired height.

g All the parts of the track, plate, brace, and trip are preferably constructed ofmetal.

The device may be attached to one side of the sashes only; but I prefer to attach in duplicate, as shown in Figs. 1 and 2, and desire to reserve to myself the privilege to make such mechanical changes in the construction of any of the parts as may be made without departing from the spirit and scope of my invention.

What I claim, and desire to secure by Letters Patent, is

The combination with an upper windowsash having recesses and shoulders integral in its side piece and a lower sash provided with a top plate having a bearing, and a lug with perforations therein, of a metal track vertical in said sidepiece and provided with flanges and an outlet at the top, a brace provided with a lug and guides upon its face and lower duplicate lugs with perforations adapting it to be pivoted on said plate-lug, a trip adapted to travel in said guides and draw the brace out of contact with the shoulders or look it when in contact therewith, thecrosspiece swiveled upon the upper end of the trip permitting the trip to be revolved, and the triplift adapted to engage with the lug on the face of the brace both to lock the device more securely or to hold the trip up and permit the cross-piece to travel freely in the track while a sash is being raised or lowered, substantially as described and for the purpose specified.

In testimony whereof I affix my signature in presence of two witnesses.
